Living dangerously, eh?  Delegations smaller than /24 are common, and it
is not possible to freely pick your neighborhood on the Internet like
one can when bying a house.

Since you are parsing IP addresses, I'd like to mention IPv6.  Picking
octets can get a bit tricky with just regular expressions.

    beowulf.gw.com has address 204.80.150.34
    beowulf.gw.com has IPv6 address 2001:14b8:1ee::34

    pyry.gw.com has address 204.80.150.129
    pyry.gw.com has IPv6 address 2001:14b8:1ef:8000::226

Being deterministic and simple, it is my favorite. :)
